ABSTRACT
Healthcare sector is facing plethora of challenges ranging from poor infrastructure to population explosions, large masses of population shifting from rural to urban area etc. Traditional facilities makes user confined thus restricts user movement especially elderly people. Our goal is to increase medical efficiency and reduce burden on healthcare infrastructure. We intend to create prototype of a wireless monitoring system which requires low investment for development and provide quality healthcare at the same time. For proposed system, Arduino Mega processor is used along with various sensors and data transmission system. Sensors used thus act as a step counter and calorie-calculator; measure body temperature, heart rate and ECG thus giving basic patient monitoring data. Attached LCD displays various health related parameters thus measured. Interactive mobile app is developed on android platform which displays parameters. Received data can be transmitted to remote location for further analysis while transmission system ensures safety during critical time’s thus providing quality assurance.
INTRODUCTION
Current method of providing medical assistance is based on person physically present in the hospital and constantly monitor physiological parameters. Lack number of doctor is the major problem in most of the hospitals and further huge workforce such as nurses, clinicians etc. are used to monitor health related data of patient.Further there are many instances where patient do not get access to medical facility due to bedding capacity issues.The proposed system is more useful for elderly people who generally have constant health related issues. Through our system there is no need of patient physically present while they can indulge in daily activities at home.Such device can also allow doctor to view data over a long period of time and find co-relation between health and received parameters.Development of patient monitoring system has been quite intensive in the past decade and there will be vast medical usefulness if implemented wirelessly.Therefore through this paper we aim to create working prototype of "SMART HEALTHCARE DEVICE", a wireless patient monitoring system using multiple sensors which receives data and transmit it to remote location.In order to track daily activities such as steps taken and calorie burnt etc, pedometer and calorie counter are incorporated in above mentioned independent systemthus effectively targeting people from various age group at the same time.Arduino Mega processor is interfaced with various sensors. In-order to get overall health related information, sensors measure body temperature,heart rate and ECG.In case of emergency,to know whereabouts of patient GPS is also introduced which gives location to concerned authority.Android based app is developed which displays aforementioned data.In order to transmit data,Bluetooth technology is used.Once transmitted data is received,it can be accessed by medical professional such as doctors,clinicians,nurses etc. and can be used for further analysis.
PROPOSED ARCHITECTURE
The proposed architecture is an integration of health sensors that would collect health related data and a mobile app to form a smart healthcare device.
*picture*
As shown in the above picture we have various health sensors like ECG, temperature sensor and heart rate monitor attached to it. The ADXL accelerometer acts like a pedometer part of the smart health care device. There is a RTC module to keep a track of date, day and time. There is also a GPS module to locate the position of a person. The processed data from each of these modules is displayed on a LCD. Each of these various modules is interfaced to microcontroller board, Arduino Mega which is based on Atmega2560. The data collected from this wireless sensor network is sent through a Bluetooth communication channel to the mobile app.
MODES OF OPERATION
All the above modules have been in divided into 3 different modes for ease of use and to facilitate and provide the use exactly what they want.Thus the smart healthcare device works in three modes. There are three switches to switch between the modes.The results of all these modes are displayed on the LCD monitor and also the Android app. The data is sent to the app with the use of a Bluetooth module.
The whole hardware set up is divided into 3 modes for two reasons.
i) Ease of use: The pedometer requires a person to be in motion while the ECG requires a person to be stationary for accurate readings. Thus by dividing the whole set up into # modes, using the device becomes easier.
ii) Waiting for interrupt: The heart rate sensor requires the controller to wait for 10 seconds before a pulse is detected. During this delay of 10 second, the controller cannot detect whether the threshold is crossed by a person’s moment and thus it cannot detect whether a step is taken or not.
CONCLUSION
Healthcare nowadays is changing and to keep up with the changing environment, we have proposedour Smart Healthcare Device. Traditionally medical assistance involves the physical presence of thepatient and doctor. With our device we have tried to eliminate this necessity to an extent thereby tending to the lack in the number of doctors and the current scenario of the infrastructure available for medical assistance. Our device works as a personal diagnostic monitor that helps keep in check the user’s health. The device has three different working modes for different application namely, the step counter and the calorie calculator; ECG monitor; Heart rate monitor along with the temperatureand GPS module for in case of emergencies. The proposed system also has an android application which displays the results of these 3 modes remotely. By this we aim in attaining remote access to the user’s medical data either by the users themselves or by the doctor. The device can be further improvised and modified to aid to a larger group of people with the addition of few more applications such as BP monitor, and a health check-up journal to keep track of one’s fitness routines and health. Presently our app isn’t protected from invasion; therefore with the addition of a safety feature in the app the data can be protected and can also be used commercially.
